Default Power for horn Relay
Wanting to install a louder horn that requires a relay. Where is the best place to get power?

If unswitched works for you, I'd suggest the terminal post on the firewall behind the battery

Is this for your '78, or do you have a locomotive? All cars (including all Corvette's) have had relays for their horns since . . . waaay back! I believe semi's have air horns, so what are you trying to do?

I served aboard the USS Enterprise. Now THAT had a loud horn!!

Thanks.
Looks to be reasonably easy to get to.
